Which pencil lead is darkest?
The darkness of pencil lead is determined by its graphite-to-clay ratio. The higher the graphite content, the darker the lead. Therefore, a pencil lead labeled as "HB" or "B" will be darker than a lead labeled as "H" or "F." The darkest pencil lead commonly available is typically labeled as "6B" or "8B," indicating a high graphite concentration.
Is pencil lead a resistor?
It is not a resistor, but not to say it's a good conductor. Although it lacks the metallic bonding that makes Cu such a good conductor, the sheets of graphite have hybridized sp2 orbitals, meaning there are long rows of p orbitals that can share electrons across the sheet, meaning it can conduct electricity. It has a resistivity of ~20uOhm meters, whereas as Cu has a resistivity of ~17nOhm meters.

What is a pencil lead made of?
Pencil "lead" is actually made of graphite, which is a form of carbon. The graphite is mixed with clay to give it form and strength. These mixture of graphite and clay are then encased in wood to create a pencil.
What is The predecessor of the graphite pencil?
The predecessor of the graphite pencil was the lead pencil, which used a mixture of graphite and clay for the core instead of just graphite. Lead pencils were first developed in the 16th century.
What mineral is a pencil made up of?
